Ever wondered if you respond to emails too slowly, or what kinds of email you receive most often? Gmail Meter is a simple script designed for Google Docs that can get to the bottom of how you communicate, statistically speaking.

What will Gmail Meter uncover? How many emails you've received and sent, what your email traffic looks like each day, your various categories of email, word count, and—my favorite—how long it takes you to respond to a message (on average). It's pretty easy to set up. Just watch the video above or follow these instructions:

Go into your Google Docs account and make a new spreadsheet. Call it "Gmail Meter."

Go to the Tools menu and choose Script Gallery.

Type "Gmail Meter" in the search box and click the Search button.

You should only have on result: "Gmail Meter" (surprise!). Click the Install button next to it and authorize the script when prompted. Once you authorize, you'll also need to grant access to the script, so go ahead and do that.
